Zusammenfassung

People are different in their expectations. Why should everyone be satisfied with a global vehicle with the same powertrain?
Therefore, the right architecture of a powertrain is under intense discussion.
Driven by significant uncertainty and volatility in the markets and in legislation, OEM expectations are shifting to scalable solutions that can be adapted to different markets, vehicle classes and still meet / support the manufacturer's DNA, both in terms of efficiency (CO₂) and performance.
The speech presents an innovative strategy implemented in the technology demonstrator e2, in which the conflicting goals of scalability and individuality are resolved. The focus is no longer exclusively on the aspect of efficiency, but holistically on the requirements for modularity and scalability with regard to CO₂, performance and driving dynamics. Concrete performance simulations for different scaling levels of the powertrain architectures are presented.
Whereas in the past the performance of the vehicle was exclusively attributed to the performance of the combustion engine and the driving dynamics of the distribution of this performance to the relevant powertrain components, the advancing electrification of the drive train opens up completely new thinking and solution approaches.
As a result, a consistent use of these degrees of freedom in combination with module and
scaling strategies leads to a considerably reduced complexity in the drive train for the OEM
and, on the other hand, even expanded diversity in terms of performance and dynamics.
